Description
Technical data (Tamb = 25 °C, UB = DC – 24 V)
ESX50D-Sxxx
The type ESX50D-Sxx is an electronic circuit protector capable of
communication, which forms the intelligent power distribution system
ControlPlex® type SVS201-CP together with the bus terminal
controller CPC10 and the power distribution board SVS201-PWR
By means of its communication interface, the measuring values
recorded by the ESX50D-Sxx will be forwarded to the CPC10 via
the proprietary device bus ELBus® and then to a superordinate
programmable control unit. This allows flexible adjustment of the current
rating and its parameters to the requirements of the system and its
direct controllability. So the user can import the relevant information
regarding his DC 24 V voltage supply and process it accordingly.
The ESX50D-S is available in two different versions. The first version
has a rotary switch to allow current rating adjustment directly on the
circuit protector in a range from 1 A to 10 A. The second version
offers this adjustment feature via a field bus system or a USB service
interface.
At a width of only 12.5 mm the ESX50D-S provides selective protection
for all DC 24 V load circuits. This is achieved by a combination of
active electronic current limitation in the event of a short circuit and
by a parameterisable overload disconnection.
A typical application is the protection of DC 24 V switched mode
power supplies which are widely used in in factory automation today.
In the event of an overload, however, they turn down the output
voltage which is intended to power all connected loads. So if there is
a failure in a single load of the system, the supply voltage will break
down also in all other load circuits. Not only does this frequently cause
undefined fault conditions, but it can even lead to machine stoppages
or system downtimes. This is exactly where the ESX50D-S comes in
by responding to the overload conditions faster than the switched
mode power supply. The max. possible overcurrent is limited to
typically 1.4 times of the selected current rating (see table 1). This
allows switching on capacitive loads up to min. 20,000 µF, disconnection
is effected in the event of overload or short circuit or at undervoltage
and overheating.
Visual status and failure indication is by a multi-coloured LED on the
protector and is transmitted to the superordinate control unit via the
communication interfaces. The manual ON/OFF swtich on the device
as well as the control units which are programmable from memory
and which are connected to the communication interfaces allow the
start-up of selected load circuits.
As soon as the ESX50D-S detects an overload or short circuit in its
load circuit, it blocks the load output transistor after a parameterisable
period of time and disconnects the current flow in the faulty circuit.
After remedy of the failure, the load output of the ESX50D-S is re-ac-
tivated by an electronic reset signal or manually by actuating the ON/
OFF switch on the device.
